The T.800 spec says there should only be one 'colr' box, but the
extended jpx file format spec in T.801 annex M allows having multiple.
Method 2 is a basic ICC profile, while method 3 (jpx-only) allows full
ICC profiles. Support that.
For the test, I opened buggie.png in Photoshop, converted it to
grayscale, and saved it as a JPEG2000, with "JP2 Compatible" checked
and "Include Transparency" unchecked. I also unchecked "Include
Metadata", and "Lossless". I left "Fast Mode" checked and the quality
at the default 50.
It's not safe to capture a local NonnullGCPtr by reference in a closure
that will execute at some arbitrary time in the future when the local is
out of scope.
I saw a suspicious null dereference in
check_if_access_between_two_browsing_contexts_should_be_reported(),
but I have no idea how to reproduce it.
Still, it seems harmless to paper over it with a FIXME debug log.
While waiting for a task that populates a session history entry, we
can't limit the processing of the event loop to the
`NavigationAndTraversal` task source. This is because fetching uses the
`Networking` task source, which also needs to be processed.
Since making a fetch request might take some time, we want to process
everything on the event loop while waiting, to avoid blocking user
interactions.
It is still possible to use `spin_processing_tasks_with_source_until()`
on subsequent steps of `apply_the_history_step()`.
Also modifies test that was flaky.
The current location of the IPC invocation is often too soon. We reach
it before the audio file has completely finished downloading / loading,
thus there isn't an AudioTrack object yet.
Instead, wait until we are actually playing the audio to invoke the IPC.
This is particularly frequent on bandcamp.
This works just like masks, with a few more (spec imposed) limitations.
All the style properties on the contents of a <clipPath> are ignored,
and instead we just paint the "raw geometry" (as all black), then apply
that as an alpha mask to the target element.
If the element has both a `mask` and `clip-path` set, we compute the
masking area as the intersection of the mask rect and clip rect, then
apply the clip mask to the `mask` (producing a combined mask).

This uses the same trick as done for masks in #23554. Each use of an
SVG `<clipPath>` becomes it's own layout subtree rooted at it's user.
This allows each use have it's own layout (which allows supporting
features such as `clipPathUnits`).
When a PutById / PutByValue bytecode operation results in accessing a
nullish object, we now include the name of the property and the object
being accessed in the exception message (if available). This should make
it easier to debug live websites.
For example, the following errors would all previously produce a generic
error message of "ToObject on null or undefined":
> foo = null
> foo.bar = 1
Uncaught exception:
[TypeError] Cannot access property "bar" on null object "foo"
at <unknown>
> foo = { bar: undefined }
> foo.bar.baz = 1
Uncaught exception:
[TypeError] Cannot access property "baz" on undefined object "foo.bar"
at <unknown>
Note we certainly don't capture all possible nullish property write
accesses here. This just covers cases I've seen most on live websites;
we can cover more cases as they arise.

We were able to keep LibCoreMinimal a bit smaller as an object library,
but that is causing ODR violations in the fuzzer build (realistically,
should be an issue in all builds, but only the fuzzer actively complains
for some reason).
To make it a shared library, we have to add a couple more symbols to it,
and make LibCore publicly depend on it.
Our implementation was errantly matching HTML tags other than the list
specified by the spec. For example, a <meta name=title> tag would be a
match for document.title.
For example, bandcamp will dynamically update its title when audio is
played as follows:
document.title = "▶︎ " + document.title;
And bandcamp also has a <meta name=title> tag. The result was that the
title would become "▶︎ [object HTMLMetaElement]".
